Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flotation machines, in particular to a impeller assembly for optimizing bubble distribution of a flotation machine. BACKGROUND

[0002] In the field of mineral flotation, flotation machines, as the core equipment, undertake the key task of separating and extracting useful minerals from ores. With the continuous expansion of mining scale and the increasing of ore processing capacity, flotation machines are always in a high-intensity continuous operation state, which puts higher requirements on the performance of flotation machines. The existing patent technology (CN119634061B) discloses a high-efficiency sorting circular flotation machine. The flotation machine is provided with a cleaning brush. When the discharge plate rotates to the horizontal state, the discharge plate is driven by the cleaning brush from the bottom to wipe the side of the discharge plate that pushes the foam, thereby wiping and dripping the sticky material to the inside of the storage cylinder, so as to keep the discharge plate outer wall clean during the flotation process and improve the quality of flotation.

[0003] However, this technical solution mainly focuses on the cleaning of the discharge plate, and has not involved the optimization of bubble distribution in the flotation process. In the flotation process, the distribution of bubbles has a crucial influence on the flotation effect. Uneven distribution of bubbles will lead to uneven contact opportunities between mineral particles and bubbles, thereby affecting the flotation efficiency and recovery rate. In the existing technology, although bubbles can be generated by stirring and air injection, the size, distribution density and combination effect of bubbles with mineral particles still need to be optimized. Especially when dealing with complex minerals or low-grade ores, the problem of uneven bubble distribution is more prominent, which leads to unsatisfactory flotation effect and affects the efficient use of mineral resources. In addition, during the long-term operation of the existing flotation machine, impurities are easily accumulated inside the equipment, which will affect the generation and distribution of bubbles, thereby reducing the flotation efficiency.
